Checking out the Hello World of Things

A Hello World program is the typical way to start the journey in a new programming language. A Hello World program on a microcontroller looks a bit different compared to a normal Hello World program. We are going to write a Hello World program to let the built-in LED blink. Let's get started!

Getting the requirements ready

To get started with our program, we need the following:

• An Arduino UNO
• One USB cable to connect it to your computer

Preparing the project

Follow these steps closely for your project:

1. Create a new folder named ch1 in the root of your project.
2. Inside the folder, we need to create a folder named hello-world-of-things and inside it, we are going to create a new main.go file.
3. Your structure should now look like the following:

As we have now prepared our project, we can go on and write our first program.
